I don't want to do autoremove, bcz last time it deleted some of the necessary tools like screen-resolution and so gpu driver etc.

For the ones you do not want to be autoremoved, run them as install in order to set them as manually installed.
For example:

sudo apt install screen-resolution-extra

What is the output of

sudo apt update

After sudo apt upgrade, now its not detecting my gpu driver and resolution forced to 1024x768 and problem is still remaining. Here is the output of update and upgrade.

Looks like Google Chrome is giving some issues. Can you amend your /etc/apt/sources.list.d/google-chrome... file to include [arch=amd64]?
It should look like this. Be sure to save the file when done.

deb [arch=amd64] http://dl.google.com/linux/chrome/deb/ stable main

The rest of your Zorin Sources appear to be running on a server that is Down in India.
Can you please open Software & Updates and set Download From: to Main server in the drop down menu?
Refresh the cache as you close out Software & Updates (It will ask with a prompt).
Then test sudo apt update again and see if you are still getting errors.

In your given location, I can't found a file like google or chrome:

Ah... Yes, the markdown language of the forum does funny things...

What is the output of sudo apt update currently?
You can use the No Parse tag on the post reply toolbar (It looks like </>) to contain those pastes.

AH I see. OOps.
This is the Mono Project, not google chrome. There's that solvable, at least. Mystery solved.
Once you do that for Mono, can you reboot,
then now that you are set to main server and with that Mono error resolved...
Run sudo apt update && sudo apt upgrade and see if it fully works?
